我已经在Windows 7 x64上安装了Qt5.12。和CMake 3.16。
我想构建OpenCV-4.1.2。因此,在cmake中,我检查了WITH_QT
并将QT5_DIR
指定为:C:\\Qt\\5.12.6
,然后单击“配置”。但是我得到这个错误:
CMake Error at cmake/OpenCVFindLibsGUI.cmake:18 (find_package):
Could not find a package configuration file provided by "Qt5" with any of
the following names:
Qt5Config.cmake
qt5-config.cmake
Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
to a directory containing one of the above files. If "Qt5" provides a
separate development package or SDK, be sure it has been installed.
Call Stack (most recent call first):
CMakeLists.txt:669 (include)"
最佳答案
我终于知道了:我在Qt目录中搜索Qt5Config.cmake
,并在以下位置找到了它:“C:\ Qt \ 5.12.6 \ msvc2017_64 \ lib \ cmake \ Qt5”。
